Solution Overview

Problem

Existing wireless communication systems face challenges in managing authentication and authorization for aerial devices without a supported interface between networks, leading to inefficiencies and compatibility issues.

Innovation Solution

A method for wireless devices to receive authentication and authorization status from a first network, indicating the absence of an interface with a second network, and send a message to the second network with a valid duration, facilitating seamless communication and authorization procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an interface between first network and second network is established for aerial service authentication, then authentication capability is improved, but device complexity and network configuration complexity increase

Engineering Contradiction:
Improveauthentication capabilityVSAvoidnetwork interface complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the authentication and authorization status information from the complex network interface communication and embeds it directly into messages that can be transmitted through existing wireless communication channels. This separates the essential authentication function from the complex N26 interface requirement, allowing aerial devices to be authenticated without establishing a dedicated network interface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent makes the existing wireless communication messages multi-functional by incorporating authentication and authorization status indicators along with validity durations into standard message exchanges. This allows existing communication protocols to serve both data transmission and authentication purposes, eliminating the need for separate authentication interfaces.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If network interface N26 is implemented for aerial device authorization, then authorization accuracy is improved, but ease of operation deteriorates due to configuration complexity

Engineering Contradiction:
Improveauthorization accuracyVSAvoidnetwork configuration ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent enables the aerial device to self-report its authentication and authorization status to the network through message exchanges. The device includes validity duration information in its transmissions, allowing the network to automatically determine authorization without complex configuration procedures. This self-service approach maintains authorization accuracy while dramatically simplifying operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent performs authentication and authorization status determination in advance, embedding the validity duration information into messages before transmission. This preliminary action allows the network to pre-evaluate authorization status, eliminating the need for complex real-time configuration and simplifying operational procedures while maintaining precise authorization control.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If traditional authentication procedures are used without validity duration indication, then compatibility with existing systems is maintained, but productivity decreases due to repeated authentication

Engineering Contradiction:
Improvesystem compatibilityVSAvoidauthentication efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent performs authentication and determines validity duration in advance, embedding this information into the initial message exchange. This preliminary authentication action with validity duration allows the device to operate without repeated authentication procedures during the valid period, significantly improving productivity while maintaining compatibility with existing systems through standard message formats.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enhances existing authentication messages by adding a validity duration parameter without changing the fundamental message structure or protocol. This parameter addition allows the system to maintain full compatibility with existing networks while enabling more efficient authentication procedures that reduce repeated authentication requirements, thereby improving productivity.

Inventive Principle:
Principle #35Parameter changes

AI summary

A wireless device receives, from a first network, one or more messages comprising: an authentication and/or authorization (AA) status of the wireless device indicating whether the wireless device is authenticated and/or authorized for an aerial service; and a parameter indicating that an interface between the first network and a second network is not supported. The wireless device sends, to a network function of the second network, a message, wherein the message comprises the AA status based on the parameter indicating that there is no interface.
